IMPROVEMENT IN SPINDLES FOR SPINNING AND TWISTING MACHINES.

Specification forming part of Letters Patent No. 156,770, dated November10, 1874; application filed September 30, 1874.

To all whom it may concern Be it known that I, EUCLID D. CARTER, of thetown of Pawtucket, county of Providence, State of Rhode Island, haveinvented a new and useful Improvement in Spindles for Spinning andTwisting Machines; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to'make and use the same, reference being had to theacccompanying drawings forming part of this specification, in whichFigure I is a vertical section through the center of the spindle,showing the suspended bolster 12, carrying the step for the spindle, theoil-reservoir'g, and the return-ducts O, and their relation to thespindle. Fig. II is an elevation of the same, showing its externalappearance, a bobbin being shown in broken lines. Fig. III is a top viewof the oil-cup cl, showing the return'ducts (J.

Similar letters of reference indicate corresponding parts.

The object of this invention is to make a spindle for spinning andtwisting machines which shall be light, firmly supported in its bolster,and surrounded by an oil-reservoir, which will supply oil for a longtime- The nature of the invention consists in rigidly securing to thebolsterrail of a spinning or twisting machine a spindle-bolster, theupper part of which forms a chamber and rests on the bolster-rail, andthe suspended part of which forms the bolster, and has a step secured tothe lower end; and surrounding this suspended step a chamber, so securedby a screw that the same may be readily removed and replaced while themachine is in motion, and so arranged that the oil may enter thesuspended bolster, and aseendin the same, and return, through ducts, tothe reservoir or bottle.

In the drawings, a is the spindle, which is supported by thebolster-tube b, and rests on the step h. The upper end of thebolstertube b has an oil-cup, formed by enlarging the diameter of thebolster, and which forms a shoulder on the same,and rests on thebolster-rail N, to which it is secured by the nut E. Surrounding thebolster-tube, and secured to the same by the nut S, is the oil-reservoirg, the interior of which communicates with the interior .of thebolster-tube by one or more holes, and with the oil-cup by the ducts O(J. The whirl K is secured to the spindle, revolves with the same, andcarries the bobbin, which is indicated in broken lines. The

spindle is prevented from lifting when the bob- I and returned to theoil-reservoir by the ducts 0. Thus a continuous circulation of the oilis produced as long as the spindle is in motion. As the oil bottle orreservoir is large, the spindle will be oiled for a long time; and asits bottom is below the step all impurieties in the oil, and all gummymatter formed by the friction and by oxidation, are precipitated to thebottom of the oil-bottle, and prevented from reaching the spindle. Allbearing-surfaces are therefore at all times lubricated with pure oil,thus insuring the free running of the spindle with the least possiblepower.

The oil bottle or reservoir 9 can be taken off, cleaned, refilled, andreplaced without stopping the machine or the spindle, by unscrewing thebottle; and for this purpose the screw portion is made four or sixsided, or may be made of any other form best suited to answer thispurpose.

I am aware that bolsters have heretofore been suspended and secured tothe bolsterrail similar to the bolster shown in my invention. This I donot claim. I am also aware that chambers have been used, formingoilreservoirs, surrounding the bolster, and communicating with the same;but such chambers could not be detached from the bolster and cleaned orrefilled while the spindle was running, and the machine had to bestopped, which-is not necessary with the arrangement as shown, andwhich'is herein described.

Having thus described myinvention, I claim as new and desire to secureby Letters Patent as my invention I The oil bottle or reservoir 9,substantially as described, in combination with the suspended bolsterI), having holes for the admission of oil near the steps, and the ductsC connecting the oil-cup with the oil-reservoir, substantially as andfor the purpose herein set forth.

EUCLID D. CARTER.
